Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed June 9,1919, Serial No. 302,739. Renewed August 27, 1921. Serial No. 496,161.

ToaZZ whom it may concern:

Be it known that I, GERARD R. MARSICO, citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Signals, of which the following is a specification.

This invention relates to signals and more particularly to an improved construction of the form of my invention shown in my application Serial No. 242,445, filed June 28, 1918, and tea furtherdevelopment of the invention disclosed in a co-pending application executed by me May 22, 1919, Serial No. 302,740.

' In my application No. 242,445, filed June 28, 1918, Iprovided a structure for augmenting the force of a rotor against avibratory member so as to produce loud sound having lasting qualities, effectuating or accomplishing such end by an arrangement of clutch devices adapted to be thrown into operative engagement with the rotor and to be subsequently released from such engagement to permit the rotor to revolve freely. For the purpose of further increasing this action of the parts I have shown and described in my application executed May 22, 1919, a plurality of sliding clutch devices adapted when in one position to engage at diametrically points with the rotor and to entirely disengagetherefrom when in a second position, the latter position serving to eliminate friction between the rotor and the clutch deviceswhile permitting the first performance of said clutch devices to exert maximum leverage action against said rotor.

Inthe construction which I will describe presently I utilize in a positive manner the of the eccentric promptly operating to become a temporary fixed part of the rotor so I have followed the same idea of an annular internal clutch surface on a rotor; positioning the same at or near the periphery of the rotor to take full advantage of the leverage action of the clutch device therewith, and I have employed correspondingly the same principle of supporting the rotor for movement independent of the clutch device.

In the present embodiment of the invention Ialso look to the compactness and simplicity of the device, employing an exceedingly small number of parts; associating the same to warrant positive operation thereof at the requisite time and establishing the mechanism as a whole which can be manufactured at a comparatively small cost.

The various important features of my inventlon will be particularly pointed out hereinafter in connection with a detailed description which I have selected for illustration in the accompanying drawings, in which similar reference characters indicate corresponding parts in the several views.

In the drawings,

Figure l is a side view of the signal showing parts broken away.

Fig. 2 is a side view of the rotor.

Fig. 3 is a side view of the combined guide and Stop disk.

Fig. 4 is a side view of the eccentric showing the ring and disk separated.

Fig. 5 is a perspective view of the rotary support.

Fig. 6 is a side view of the rotor showing a slightly modified form of the invention.

10 represents a case provided with a resonator 11 and vibratory member 12, the latter having an anvil 13 adapted to co-act with a striking surface 14 of a rotor 15.

The rotor is mounted to revolve freely on a cylindrical extension 16 of a rotary support 17 which is freely arranged on a fixed axle 18'carried by a bracket structure 19. The bracket structure is arranged in the case 10 in any well known suitable manner and it carries a guide 20' having a sliding plunger 21. This plunger has teeth 22 meshing with a gear wheel 23, the latter mounted upon a shaft 24 carried by the bracket structure 19. This shaft also supports a gear wheel 25 which meshes with a pinion 26 which constitutes a fixed part of the rotary support 17. In this manner power will be transmitted to said rotary support when the plunger 21 is actuated,

The rotary support has an extension 27 of substantially rectangular form and said extension is fixed in a corresponding opening 28 formed at the center of a combined guide and stop disk 29. While it will be observed that the rotor is free for movement independent of the rotary support 17 it will likewise appear that said disk 29 remains always fixed. On the extension 27 at a point between the rotor 15 and said disk 29 is an eccentric 30 consisting of a disk 31 fixed to said extension and a ring 32 embracing said disk and provided with a fixed clutch dev ce 33. This device has an effective gripping surface 34 adapted to engage with the annular internal clutch surface 35 of'therotor. A spring 36 is employed for normally holding the plunger elevated. The disk 29 carries a suitable guide 37 which accommodates the clutch device 33 in its movements while holding the same normally to one side of a the rotor. so

When pressing the plunger downward motion is conveyed to the eccentricto raise thehigh side of the disk 31 with respect to the horizontal center of the rotor and in consequence thereof the surface 34 of the clutch device is moved into firmgripping engagement with the annular surface 35 of the rotor, temporarily looking or securing the two parts together and thus causing effective actuation of the strikingsurface of the rotor against the anvil of the diaphragm. The force of the leverage action is considerable and the pulsations induced in the diaphragm give life to sound of great amplitude and intensity. When the plunger returns to its normal-position, the eccentric does likewise, again restoring the relativev inactive positions of the surfaces 34 and 35 to permit the applied power contributed to the rotor to cause the latter to freely revolve by inertia.

In the modified form of the invention shown in Fig. 6 theeccentric consists of a 1 disk 39 having a flat side 40. The ring 41 is Provided with a corresponding fiat side 42 adapted to co-act'with the side 40 to form a stop to limit the movement of the clutch device 33 in an annular direction.

While I have herein shown and described and have pointed out in the appended-claims certain novel features of construction, arrangement and operation whlchcharacterlze the materials used, and of their operations may be made'without departing from my invention.
